Site description The IBA is the only remaining large riverine forest on a free flowing stretch of the Danube in Austria. Close to the river Salix and Populus dominate, whilst in other areas the forest is dominated by Fraxinus, Quercus and Ulmus. Artificial Populus plantations have replaced the natural forest in many places. The forest is interspersed with oxbow lakes, fringed by reedbeds (Phragmites). Human activities include forestry, recreation and angling.

Key Biodiversity The site is important for forest species, particularly breeding raptors and woodpeckers.
